Florida's Corrections Department has provided extra security to Casey Anthony since she is one of the most hated women in America, a probation spokeswoman said Thursday.

Anthony reported for the first time to a probation officer on Wednesday at 6 p.m. and was polite and cooperative, ssid Gretl Plessinger.

Anthony, 25, the Orlando mother who was acquitted of killing her 2-year-old daughter Caylee, must serve a year's probation in Florida, after being convicted of check fraud charges. During the murder trial she received death threats.

The visit lasted a little over an hour. The probation officer laid out for her in detail the conditions of the court. She understood those conditions. She told the probation officer that she intended to do well on probation. She was polite and cooperative, Plessinger said.

Anthony met the probation officer without the presence of her attorneys. It is unclear whether she arrived with someone or was alone at the probation office.

Anthony must report within the first five days of each month to her probation officer, but her information will not be entered into the state probation database to keep her location secret for security reasons.

Because of the death threats against her and the court orders, we are taking security into consideration in this case certainly and we will not be disclosing the location or anything that will lead to the discovery of her location. But she will be treated like every other offender in that if she doesn't follow the court orders, we will immediately notify the court, Plessinger said.

The court made a pretty strong statement talking about the fact that she's one of the most hated women in America, Plessinger said of the security measures.

Defense attorney Jose Baez told Fox News Anthony will serve probation somewhere in the state of Florida and will have to take classes online.

Anthony was released from the Orange County Jail on July 15, after her acquittal. Since then her only confirmed whereabouts have been in Ohio and Florida.

In July 2008, just a month after Caylee died, Anthony stole a set of checks from her friend, Amy Huizenga, and used them to buy several hundred dollars' worth of clothes and groceries. She pleaded guilty to fraud and was sentenced to a year's probation in January 2010 -- but she got a reprieve from serving it while her murder trial was pending.

Earlier in August, Judge Belvin Perry ruled out that Anthony had time until Aug. 26 to return to Florida to serve a year's probation for a check-fraud conviction, upholding a sentence by Judge Stan Strickland.

Anthony's lawyer filed an appeal in Daytona Beach with Florida's Fifth District Court of Appeal, which says that she had already served her year's probation while she was in jail awaiting her murder trial.

Judge Stan Strickland at the time of Anthony's check fraud plea said that she would serve a year of probation after her release from jail, but forgot to repeat that in his final order.

Strickland was in charge of Anthony's murder case until 2010, but he stepped down at the request of her defense team.
